Current sensors are designed to monitor the presence or absence of AC or DC current and are available in an assortment of standard & custom models with hermetic or gasket seal models designed to withstand severe environmental conditions.

The IPC series are digital, precise phase current sensors with a wide range of possible applications. Different designs with different measurement ranges between 100 Ato 2,500 Aare available.Because of this modular principle of the shunt-based phase current sensor, we are able to offer our customers a quick solution for the requirements. Due to their high bandwidth, high linearity and very low temperature coefficients, our modules are perfect for the high-precision current measurement in modern control systems and converters.

API Technologies offers a wide range of current sense transformers that measure electrical current (AC & DC) and can transform current from high to low measurable values. API series 5300 current sense transformers are available with current ranges from 3.5 to 800 amps in six subcategories of current sense transformers.

The Current Probe measures DC and low-frequency AC currents up to 600 mA. Use Current Probes in combination with Differential Voltage Probes to investigate Ohm's Law and explore series and parallel circuits. The 0.1 shunt resistor minimizes changes to your circuit. If currents will exceed 1 A, use the High Current Sensor.

The robust IRF current probes all utilise a flexible clip on current sense coil, allowing fast and safe installation, ideal for current monitoring and retrospective fitting. Many of the current transformer safety considerations can be eliminated using this technique, which produces safe low level signals even with no secondary burden or loading.

Innovar Current Sources are the standard in the circuit breaker industry. Our Current Sources supply regulated current from 1 amp to 100,000 amps with incredible accuracy, along with providing a full set of features that is unmatched by any other Current Source in the market.

Accurate sensing of currents is central to enhancing application safety. Controlling the current within set boundaries avoids overheating and short-circuits. Current measurement is also an essential part of energy metering.

The ACP 1000 SM current probe has been designed for use with multimeters, recorders, power analysers, safety testers etc. for accurate non intrusive measurement of AC current. Using the latest transformer technology, the SM 1000A/1A can measure currents from 100mA to 1500A over a frequency range of 30Hz to 10kHz.

Leakage current measurement in transformerless PVinverters● First human contact protection of PV arrays● Failure detection in power sources● Symmetrical fault detection● Current leakage detection in stacked DC sources● Single phase nominal current measurement up to ±35 A perwire (DC or AC).

Summation CTs are designed to summarize several synchronous Alternating Currents of equal phase relation. They are used to add secondary currents of several main CTs in order to measure with one CT only. That means the primary currents are added & divided by the number of inputs
